Description

Technical Field

[0001] The present application relates to the field of industrial smelting, and in particular to an axial water discharge induction melting furnace. Background Art

[0002] This section is intended to provide a background or context for the embodiments of the present application as stated in the claims. The contents in this section are for reference only and do not constitute an admission or confirmation that they are prior art that has been disclosed.

[0003] A medium frequency melting furnace is a type of equipment used for metal melting, and is widely used in the melting and refining of non-ferrous metals such as steel, copper, and aluminum. A medium frequency melting furnace utilizes medium frequency electromagnetic induction to heat the metal. Its main features are fast heating speed, high efficiency, and precise control of the melting process. Traditionally, a melting furnace pours molten metal into a crucible in a parabolic form through the furnace mouth. However, this traditional method has certain defects in maintaining metal quality and melting efficiency. The traditional pouring method has a large height difference, which causes the metal to pour out quickly, easily generating splashes and impacts, increasing metal loss and environmental pollution. The large contact area between the molten metal and the air leads to rapid heat loss and metal oxidation, thus affecting product quality and casting efficiency. Summary of the Invention

[0004] The purpose of the present application is to provide an axial water-discharge induction melting furnace, in which the molten metal liquid can flow out smoothly and naturally, so that the water discharge process is as smooth as possible, reducing loss and splashing.

[0024] Furthermore, the water outlet of the top cover is connected to the inner cavity of the water outlet shaft channel, which can ensure the smooth flow of molten metal and greatly reduce the metal splashing and impact in the traditional pouring method. In addition, the forward tilting cylinder and the backward tilting cylinder can make the operation of the medium frequency furnace more diversified, taking into account the functions of slag skimming and pouring out molten iron.

[0025] Furthermore, the smelting process is further optimized by the slag removal platform and dust removal hood. The slag removal platform makes the cleaning of slag more convenient and safer, and the dust removal hood effectively reduces dust and impurity emissions during operation, while also providing effective thermal insulation.

[0045] In order to better understand the technical solution of the present application, a specific example is provided below for illustration. The details listed in the example are mainly for ease of understanding and are not intended to limit the scope of protection of the present application.

[0046] The intermediate frequency furnace base 2 of the intermediate frequency furnace body 1 is installed on the civil engineering foundation. The intermediate frequency furnace base 2 is equipped with a rearward tilting axis 5, which provides the first rotation center when tilting forward, allowing the entire furnace body to rotate around this axis for rearward tilting and slagging operations. The intermediate frequency furnace bracket 3 is installed on the intermediate frequency furnace base 2 and is connected to the intermediate frequency furnace body 1 via a bearing seat 6 and a slewing support seat 7 respectively provided on both sides. The bearing seat 6 and slewing support seat 7 provide the second rotation center for the furnace body when tilting forward.

[0047] The furnace body, serving as the primary carrier for smelting metal in the intermediate frequency furnace, houses an inductor and a magnetic yoke. A top cover 8 is partially pressed against the top of the intermediate frequency furnace body 1. This leaves a portion of the opening above the furnace body 1 open, while the other portion and the top cover 8 form a molten metal chamber.

The water outlet shaft channel 9 is a circular steel sleeve, which is cast into an internal circular channel through refractory material. When the furnace body tilts forward, the molten metal liquid gradually fills the metal liquid containing chamber and flows out through the water outlet shaft channel 9 located on the side. A ceramic fiber blanket is used as a sealing gasket 11 at the interface between the water outlet of the top cover 8 and the water outlet shaft channel 9, and is pressed and sealed with a clamping flange 12 to ensure that the molten metal liquid does not leak. A solid shaft and a hollow shaft are installed in the first ear seat 14 and the second ear seat 15 installed on the furnace body platform 13, respectively.

The first end of the water outlet shaft channel 9 is connected to the top cover 8, and the second end is placed on the inner ring of the bearing seat 6 by its own weight. When replacement is needed, the clamping flange 12 is loosened, the water outlet shaft channel 9 is removed and replaced.

[0049] The drive mechanism includes a forward tilt cylinder 18 and a backward tilt cylinder 19, which provide power support for the forward and backward tilt of the furnace body, respectively, ensuring operational flexibility and reliability. During backward tilting, the slag removal platform 16 joins the tilted furnace platform 13 to form a single unit, and the slag in the furnace body is removed through the furnace nozzle and onto the slag removal platform 16.

[0050] A dust hood 17 is provided on the top of the intermediate frequency furnace body 1. Together with the top cover 8, it forms a complete protective cover above the furnace mouth. The dust hood 17 has the dual functions of dust removal and heat preservation. The rotating shaft of the dust hood 17 allows the dust hood 17 to operate accordingly according to the different states of the furnace body, such as forward tilt, backward tilt, and open furnace cover.

[0051] Through these innovative structural designs, the induction melting furnace of the present application significantly improves the operational safety, environmental protection and economic efficiency of the melting process, and achieves comprehensive optimization of the melting process.
